For question F.17 on the problem sets, what is the difference between formula mass and molar mass?

The difference between molar mass and formula mass is that formula mass is the sum of all the atomic weights of the atoms in its empirical formula while molar mass is just the mass of 1 mol of a substance. Molar mass also uses the units g/mol while formula mass uses atomic mass units (amu).

Formula mass is when you add together the molar mass of every element in the formula.
